i bought my first arrow a couple weeks ago. i was so excited to finally get one i saw it at the store and told them to bag it up. i noticed when i got it home that the right pectoral fin was broken off almost completely. it still had the "fin" part, but right where the extension starts it was severed. I don't know if i wasn't there at the store and i just wasn't paying attention or if it happened when they were bagging it up (dumb mistake i know). anyway, i call him "lefty" now. I was wondering how quick/if it will grow back and if i should use melafix on it to accelerate the process. im sure if it does grow back it will be deformed, so any advice for me?
